Service Agreement

Welcome to Fasting App, a fasting timer, tracking, and general wellness education app provided by ZeroOne Studio. Please read this Service Agreement carefully before using the app. If you do not agree with this agreement, please stop using the app.

1. Acceptance

By downloading, accessing, or using Fasting App, you agree to this Service Agreement and our Privacy Policy. We may update this agreement from time to time. Continued use after an update means you accept the updated agreement.

2. App Purpose

Fasting App provides tools for fasting timers, fasting plans, history, basic statistics, optional weight entries, reminders, widgets, Live Activities, and general educational content about intermittent fasting.

Fasting App is a self-tracking tool. It is not a medical device, medical service, diet treatment, diagnosis tool, or emergency service.

3. Important Health and Safety Disclaimer

• Fasting App does not provide medical advice, diagnosis, treatment, personalized nutrition advice, or emergency assistance.
• Fasting plans, fasting stages, timers, reminders, statistics, and educational content are general information only. They are not tailored to your medical history, medication, age, body condition, eating disorder risk, pregnancy status, or other personal health factors.
• No feature in the app guarantees weight loss, fat loss, metabolic improvement, disease prevention, disease treatment, or any other health result.
• Fasting may not be appropriate for everyone. Do not fast without medical guidance if you are under 18, pregnant, breastfeeding, underweight, recovering from or experiencing an eating disorder, have diabetes, have hypoglycemia risk, have major heart, kidney, liver, digestive, hormonal, metabolic, or mental health conditions, or take medication affected by food intake.
• If a healthcare professional has advised you not to fast, you should not use the app to start or continue a fasting plan.
• Stop fasting and seek medical advice if you feel faint, confused, unusually weak, have chest pain, severe dizziness, persistent vomiting, abnormal heart symptoms, signs of dehydration, or any symptom that feels strong, unusual, or unsafe.
• For urgent or emergency health concerns, contact local emergency services immediately. Do not rely on the app for emergency decisions.
• You are responsible for deciding whether fasting is appropriate for you and for using the app in a safe, reasonable, and lawful manner.

4. Educational Content and Estimates

Educational articles, fasting stage labels, progress rings, completion percentages, calorie-free drink suggestions, and similar information are approximate and for general reference only. They may vary based on meal composition, hydration, sleep, activity, medications, medical conditions, and individual response.

The app may help you record your routine, but it cannot evaluate your personal medical risk or tell you whether fasting is safe for your individual situation.

5. Accounts, Data, and iCloud

Fasting App does not require a ZeroOne account. Your app records are primarily stored on your device. If iCloud sync is enabled or available, app data may be stored in your private Apple iCloud account through Apple CloudKit. We do not operate a separate account server or self-operated database for your personal fasting records, weight entries, notes, or reminder preferences.

You are responsible for managing your device, Apple ID, iCloud settings, backups, and deletion of app data. Disabling iCloud sync or deleting the app may affect whether data remains available across devices.

6. Subscriptions and Purchases

Some features of Fasting App may require Fasting Pro, a paid subscription, lifetime purchase, or other in-app purchase.

• Auto-renewable subscriptions are billed through your Apple ID and renew automatically unless canceled at least 24 hours before the end of the current billing period.
• You can manage or cancel subscriptions in iOS Settings > Apple ID > Subscriptions.
• Lifetime purchases are non-renewing purchases that unlock the eligible Pro features for the app version and platform scope described at purchase time.
• Payments, refunds, billing issues, trials, and subscription management are handled by Apple under Apple’s App Store terms.
• Prices and included features may change. Changes will not reduce access already required by applicable law or Apple rules.

7. Acceptable Use

• You may use the app only for lawful, personal, and non-commercial purposes unless we give written permission otherwise.
• You must not attempt to reverse engineer, interfere with, misuse, or bypass purchase, security, or entitlement mechanisms.
• You must not use the app in a way that violates laws, third-party rights, or Apple platform rules.

8. Intellectual Property

The app, interface, design, software, text, graphics, and other content provided by ZeroOne Studio are owned by us or our licensors and are protected by applicable intellectual property laws. You retain rights to your own records and notes that you enter into the app.

9. No Warranty

Fasting App is provided on an “as is” and “as available” basis. We do not guarantee that the app will be uninterrupted, error-free, perfectly accurate, or suitable for your individual health condition or goals. Timer estimates, fasting stages, statistics, and educational content are approximate and for general reference only.

To the maximum extent permitted by law, ZeroOne Studio will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, health outcomes, or business opportunities arising from your use of or inability to use the app.
